In a groundbreaking achievement, a research team led by Professor Chan Chi-hou from the City University of Hong Kong (CityU) has made a significant leap forward in antenna technology. By developing a universal metasurface antenna, the team has successfully enabled the manipulation of all five fundamental properties of electromagnetic waves through software control. This extraordinary advancement opens up endless possibilities in the field of wireless communication systems, particularly in the development of 6G technology. The team’s research, published in Nature Communications, has set the stage for applications such as real-time imaging, wireless power transfer, and highly secure information systems.
As the world progresses towards the development of 6G wireless communication systems, the universal metasurface antenna holds immense potential. Unlike traditional antennas that only manipulate one or two properties of electromagnetic waves, this new technology allows for the independent and simultaneous manipulation of amplitude, phase, frequency, polarization, and direction of electromagnetic radiation. This level of waveform manipulation capabilities brings unprecedented flexibility and opens up new avenues for integrating sensing and communications.
Enhanced Security Features
One of the key advantages of the universal metasurface antenna is its enhanced security features. The inherent direction modulation properties of the antenna not only improve privacy but also make it an ideal candidate for eavesdropper-proof communications. The ability to independently control multiple properties of electromagnetic waves adds an additional layer of security to wireless communication systems, making it extremely challenging for unauthorized individuals to intercept or decode sensitive information.
The universal metasurface antenna offers a wide range of applications in next-generation information systems. Its advanced waveform manipulation capabilities make it an ideal component for large-capacity, high-security information systems that require real-time imaging. The antenna’s ability to simultaneously manipulate multiple properties of electromagnetic waves enables the creation of highly efficient and adaptable systems. Furthermore, the antenna’s low power consumption and high integration potential make it an attractive option for simplified information transmitters.
The Research Team
The successful development of the universal metasurface antenna was made possible through the collaboration between CityU and Southeast University. The joint expertise and resources from both institutions proved essential in tackling the complex research challenges and achieving groundbreaking results. Professor Chan emphasized the importance of this partnership, highlighting how it brought together diverse perspectives and knowledge. The team consisted of Professor Wu Gengbo, a member of CityU’s Department of Electrical Engineering and the State Key Laboratory of Terahertz and Millimeter Waves (SKLTMW), who was the first author of the paper. Co-first author Dr. Dai Junyan, a former postdoctoral fellow with SKLTMW, along with Academician Cui Tiejun and Professor Cheng Qiang from Southeast University, also played integral roles in the research.
The breakthrough achieved by the research team marks a significant milestone in antenna technology and paves the way for exciting possibilities in the future. By manipulating all fundamental characteristics of electromagnetic waves, the universal metasurface antenna revolutionizes the field of wireless communication systems. Its potential applications range from improving information security to facilitating real-time imaging and wireless power transfer. As the world progresses towards the development of 6G technology, this remarkable achievement sets the stage for further innovations and advancements in the field of wireless communication. With its ability to manipulate multiple properties of electromagnetic waves, the universal metasurface antenna is poised to shape the future of wireless communication systems.
